Mudbloods and How to Spot Them was a book by Barrett Fay[1] which presumably contained propaganda supporting discrimination against Muggle-born witches and wizards. Dolores Umbridge kept a copy in her desk[2] at the British Ministry of Magic's Senior Undersecretary to the Minister for Magic's office in 1997.
